I am a Web and Data developer based in Montreal,

With several years of experience as an analyst-programmer, particularly in web development, I have acquired solid expertise in data collection, extraction and transformation.
I mainly use languages ​​such as Python and SQL but I handle many other languages ​​and tools.

My career has allowed me to work on projects ranging from the automation of data collection processes to visualization, while ensuring the quality and integrity of the data.
I use both the cloud and native tools for setting up architectures. I have also validated my associate data engineer certificate on AWS.
My skills revolve around programming, data analysis, relational and non-relational databases, and the use of Big Data tools such as Hadoop and Spark and their ilk.
Here are some certificates that demonstrate my practical and theoretical knowledge. I am always in permanent learning. This allows me to embrace any possible challenge.

Full Stack & Data Developer with experience in PHP, Python, JavaScript/TypeScript, and modern frameworks. I work on systems involving data ingestion and transformation, API development and integration, and front‑end performance optimization.
Comfortable with relational and NoSQL databases (PostgreSQL/PostGIS, MySQL/MariaDB, DynamoDB), I structure and expose data reliably and efficiently.
Experienced with cloud environments (AWS, GCP, Azure) and distributed architectures, I enjoy improving application performance, strengthening data quality, and contributing to robust and evolving technical platforms.
I have also worked with additional technologies such as Java SE, C#, Android, iOS (Swift), and C/C++, but I focus my profile on the technologies most used in my recent roles.
